This comprehensive study examines the application of computational techniques in economic modeling and forecasting, focusing on the impact of monetary policy on key economic indicators such as inflation and GDP. The paper begins by introducing the field of financial modeling and forecasting. The research explores a range of fields of machine learning methods, big data analysis, agent-based modeling, and dynamic stochastic general equilibrium (DSGE) models before defining and exploring the theoretical foundation’s traditional econometric techniques that have historically been used for economic forecasting, examining the predictability of inflation and GDP Through detailed case studies and valuation estimates analysis, the analysis builds strength and emphasizing the challenges of these estimation methods. It also explores ways to combine different models to increase forecast accuracy and address the uncertainty inherent in monetary policy. Finally, the paper discusses future directions in cyber investment modeling, outlining emerging trends and the potential of these techniques to transform investment decision-making.
